- •
Forced convection in flat-plate microchannels filled with porous media is studied.
- •
Viscous dissipation, first-order velocity slip and temperature jump are considered.
- •
An analytical solution for Darcy–Brinkman flow model and LTNE condition is derived.
- •
Closed-form expressions for the viscous dissipation and Nusselt number are shown.
- •
A complete parametric study is conducted for air-saturated porous media.
